I would like tabs in #Logseq too but for now you can use the Tabbed Sidebar plugin, look at my screenshots here:
About organizing stuff, Logseq is definitely better than Obsidian, that is more a document editor + basic file manager.
In Logseq outliner UI you can organize everything you want hierarchically, even live queries, see the image:

FYI FlatHub uses GitHub Actions, you can check how they build their apps and some of them support reproducible builds, just in case you want to verify GitHub isn’t acting maliciously.
FlatHub and AUR can’t really be compared in terms of security. Flatpak apps also don’t modify the host OS, while AUR packages can.
Personally, I only trust distro packages and FlatHub.
